2 or Auto

[truckguy82]

what do ya know, it says AWD

I'm not trying to get into this battle but I noticed something interesting. I have a 2016 LTZ. The off-road screen does show the shaft going forward from the transfer case lit up all the time. When you engage AUTO the whole front end lights up as a mirror image of the rear end. This is the same for 4 hi. Someone (I think a GM tech) pointed out the shaft going forward from the transfer case is always engaged and the image would tend to corroborate that. I will say I used AUTO recently due to ice sleet and snow and for got about it. A few days later I cut it off and other than the reduction in resistance I couldn't tell the difference. I was going over 70 when I realized it was still engaged.

I made this point in post 95 and 108. I think it may be why there is some confusion about them being the same as AWD trucks to some.

Btw Jon, since you are monitoring this thread, I wanted to let you know I called you out a few weeks ago about where the 6.2's make power. You said the intake and exhaust. I called BS on you thinking thats impossible it has to be the manifolds.

 

Well did you look at the blackbear intake test? I was wrong! I couldn't believe it.

 

Sorry, I haven't felt like looking at those in detail yet. I'll get around to it.

This is a question for everyone with the electronic transfer case control knob on thier dash. Do you normaly have use 2 wheel or Auto for every day driving? My saleman told me to use Auto for extra safety. But I am wondering if that is really necessary.

2 in the summer, auto in the rain and winter that's how's I've been doing it since my envoy, is it the right way who knows

You'll want auto in rain if keeping those crappy stock tires on.

There is a thread on here with a million replies debating what to do. I think you should do what ever you like. I kept mine in 2 till I was in the rain or pulling my boat out of the water. Basically I put it in auto when ever I think 4 could be needed

I use auto 4wd like I would use 4X4. I have good tires and use 2wd for most of the year.

Probably because some people don't know so they're asking on this forum (which is what it's for) to find out the answer to their question. That would be my guess.

Auto 4wd if you're an idiot.

Auto makes the front drive line be engaged. The truck drives more sluggish and it consumes more fuel. Owner's manual even states this. I treat Auto like "Subaru mode". IE- light off-road, rain, etc. normal dry driving is 2wd. I will say that I've never had a truck with an auto transfer case, and thought it was a gimmick. After owning my truck i won't buy one w/out it. Made me a believer. Especially when I had the SRA's and in the FL summer and it always raining. Very good feature when properly used.

[hurricanoday]

I never noticed my truck being sluggish at all, about every time I had it in auto I didn't realize it till I randomly looked down to notice it. I also didn't notice much difference if any at all in mpg. maybe .000001 difference

Because no one uses the search feature...

 

Its easier for them to just ask than spend 2 minutes looking for the same question.
